[15] k 1 is the rate constant for chemical uptake from water at the respiratory surface (L*kg −1 *d −1). [15] C WD is the chemical concentration dissolved in water (g*L −1 ). [ 15 ] k 2 ,k E ,k G ,k B are rate constants that represent excretion from the organism from the respiratory surface, fecal excretion, metabolic transformation, and ...
Tris (pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound (C6F5)3B. It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the BC3 core is planar. It has been described as the “ideal Lewis acid ” because of its high ...
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
The FIA Formula 3 Championship season consists of a series of races, divided to Feature (long distance) and Sprint (short races). Each winner is presented with a trophy and the results of each race are combined to determine two annual Championships, one for drivers and one for teams.
Oil conversion factor from m³ to bbl (or stb) is 6.28981100 Gas conversion factor from standard m³ to scf is 35.314666721 Note that the m³ gas conversion factor takes into account a difference in the standard temperature base for measurement of gas volumes in metric and imperial units.
Periodic table. The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are ...

The quality-adjusted life year (QALY) is a generic measure of disease burden, including both the quality and the quantity of life lived. [1][2] It is used in economic evaluation to assess the value of medical interventions. [1] One QALY equates to one year in perfect health. [2] QALY scores range from 1 (perfect health) to 0 (dead).
